Summary

Children treated for a brain tumor (BT) or acute lymphoblastic leukemia (ALL) show elevated rates of working memory impairment. Working memory (WM) is the ability to hold and manipulate information online; for example, when an individual mentally rehearses a phone number in order to dial it without writing it down. A computer-based working memory intervention has been successful in children diagnosed with ADHD and stroke survivors. Individuals participating in the intervention showed improvements on working memory measures as well as more complex problem solving skills. Neuroimaging (brain scans) conducted before and after training showed changes in brain activation suggestive of underlying changes in brain systems that support working memory. This study investigates the effectiveness of this computer-based working memory intervention for childhood cancer survivors.

Detailed description

Participants randomized to the intervention arm will complete the computerized working memory training program. This computer-based training program is completed in the home and requires approximately 30 minutes every weekday for five weeks. The program software guides the child through eight rotating exercises each day, with increasing difficulty based on the child's level of performance. Exercises train both visuospatial and verbal WM using child-friendly activities. A research team member will serve as a coach who monitors weekly progress online and offers support through weekly phone calls with the study participants and their caregivers. This individual will not complete post-intervention assessments to maintain study blind. A home computer with internet connection and speakers is required. A laptop computer and/or wireless internet access will be provided to families whose only obstacle to participation is lack of computer access or internet connectivity in the home setting. Families randomized to the WM intervention will complete a tutorial with study staff that provides instruction in using a computer, the internet and the WM training software. The objective of this study is to investigate the benefits of this working memory intervention in a sample of childhood cancer survivors and look at brain-based changes that may occur as the result of working memory intervention. To achieve this goal, we plan to study childhood cancer survivors randomly assigned to the working memory intervention or a passive waitlist. Both groups will participate in cognitive testing pre-, post-, and six months post intervention. Intervention participants will also partake in neuroimaging exams before and after the intervention. Findings from this study have direct potential to support a nonpharmaceutical cognitive intervention for cancer survivors that is a safe and effective alternative to stimulant medications with great promise for improving quality of life.

Interventions

Type	Name	Description
BEHAVIORAL	Computerized working memory training program (intervention)	A computer-based training program will be completed in the home. This program requires approximately 30 minutes every weekday for five weeks. The program software guides the child through eight rotating exercises each day, with increasing difficulty based on the child's level of performance. Exercises train both visuospatial and verbal WM using child-friendly activities. A research team member will serve as a coach who monitors weekly progress online and offers support through weekly phone calls with the study participants and their caregivers). Intervention participants will also partake in neuroimaging exams before and after the intervention
BEHAVIORAL	Computerized working memory training program (control)	Participants randomized to the control group will not complete any intervention during the intervention time period and will not partake in neuroimaging exams. They will complete an immediate and six month post follow-up cognitive assessment. Following completion of these assessments, they will be provided the opportunity to complete the computer-based training program off study.
